The IT website has some information on accomodation, I can't recommend any in particular being only a visitor to the area rather than a local, but there have been a lot of developments in the past number of years and some seem to have been geared toward the student market, I have noticed that some of the Apartment blocks near the train station and football grounds seem to have been anyway. I'd recommend your neighbour get onto the Tralee IT site and it may give some pointers.
